Synopsis: High pressure will weaken over the southeastern Gulf of Mexico late tonight and tomorrow, as a mid-latitude trough pushes in over the east before stalling over north-central Florida. A weak pressure pattern will become established across the Florida Keys coastal waters Wednesday night through much of the weekend. Gentle easterly breezes tonight through Wednesday morning will become light and variable across the marine zones by Wednesday evening. Rain and thunder chances will remain elevated through the end of the work week, with slow reductions in rain chances over the weekend and into early next week.
